When Kristen Bell was 18 years old, her mom sat her down and explained that depression ran in the family: "She said, 'There is a serotonin imbalance ... and it can often be passed from female to female,'" the actress recounted in a recent interview on Off Camera with Sam Jones. Bell's mom, a nurse, also warned her that people might shame her if she ever decided to take an antidepressant—which is why Bell is so open about being on medication: "You would never deny a diabetic his insuln, ever," she told Jones. "But for some reason when someone needs a serotonin inhibitor, they're immediately crazy or something."
